03 F250, 5.4. You put a new fuse in and it pops after driving for awhile.. any thoughts. Fuse for the guages, speedo, stuff like that

 

Perhaps worn insulation on a wire that is allowing a short to ground?

definately what I'm looking for, but dont know if there was a common rub problem

 

Which fuse number? What does the owner's manual say that fuse protects?

 

Apparently it's the dash Illumination fuse.

Did you add anything to that circuit?
Does it pop with the truck sitting still in the driveway, or do you have to get it shakin' around, first?

 

It pops while driving, so I assume something is rubbing. taking a look at it today. Alternator and Battery were recently changed

 

if you want assistance, you HAVE to answer questions that are asked to guide you to a conclusion.

 

Just to clarify projectSHO89 is asking which fuse is blowing ?

Passenger Compartment Fuse 35 or Passenger Compartment Fuse 41 or both ?

 

passenger compartment, #45.. it says its a ignition fuse of some sort... I traced a battery wire that comes up to the firewall and connects to a wire that goes into the ****pit. It was badly corroded and upon inspecting it the eyelet broke off. I spliced the two wires together and let the truck go. I took it down the backroad and back, bumps and such, it never went out again.....

 

and yea I know, but today was the first time I got to look at the truck.... so THANKS

 

If it happens again, remove the steering column shroud and inspect the little harness that comes our of the shift lever tube. It's the most common reason for that particular fuse to blow.

F45 also provides power to the instrument cluster's computer.

 

popped again

 

was indeed the OD switch wire that feeds through the shifter lever....
